Missfire count question.

[Lonniesgt]

I took a pic from my forscan datalog. It does seem that lund turned off some stuff in my tune. Even the ltft. Anyways I see cylinder 4 has a 25missfire count and other cylinders look pretty good. Is that missfire count really high or low and what are some possible things to look for that can cause it. Thanks for any help.

Some amount of misfires detected is pretty normal. You should only really be concerned if the number is regularly increasing during a drive cycle. Seems a handful of misfires are common when it's moving the imrc plates around.

Ok, thank you.
